Toothbrush holder

ABSTRACT

A toothbrush holder for a toothbrush having an enlarged handle, for example a battery operated toothbrush, is provided which comprises at least one support aperture, the or each support aperture being expandable or has at least part thereof restricted in a lateral dimension compared to a width of the enlarged handle. The support aperture is suitable to support the toothbrush vertically with a bristle-end suspended downward therefrom and spaced from a lower drainage surface. The holder may also comprise a locating aperture to locate the toothbrush within the support aperture. In one embodiment, the holder comprises a housing having a removable wall with at least one support aperture for a toothbrush having an enlarged handle on one surface of the wall and preferably at least one retainer for retaining a conventional toothbrush on an opposite surface of the wall.

FIELD OF THE INVENTION

[0001] THIS INVENTION relates to a toothbrush holder for storing at least one toothbrush having an enlarged handle with bristle-end oriented downward and spaced from a drainage surface.

BACKGROUND OF THE INVENTION

[0002] Toothbrush holders function to store toothbrushes when not in use in an orderly and reasonably sanitary manner. Storing toothbrushes vertically may reduce the area required to store the toothbrushes and also enables positioning of a bristle-end of a toothbrush away from contact with potentially unclean surfaces, for example a counter or bench top.

[0003] Toothbrush holders in the past have been designed to accommodate a conventional shape of a toothbrush wherein the toothbrush has a slender handle.

[0004] U.S. Pat. No. 4,978,003 relates to a toothbrush holder with two separable parts to facilitate the access to an interior thereof. A bottom part has a disposable receptacle therein to receive drainage from a toothbrush held by the holder. A bristle-end of the toothbrush is located upwards external to the holder and a handle-end of the toothbrush is located internal to the holder. Accordingly, drainage from a toothbrush flows down the handle-end of the toothbrush to be collected in the disposable receptacle.

[0005] U.S. Pat. No. 5,769,245 relates to a toothbrush holder comprising a rack with a protective dome shaped cover to prevent contaminants from contacting the bristle-end while permitting passage of air for drying. Toothbrushes are stored vertically with the bristle-end of the toothbrush upwards within the protective cover. A toothbrush stored in this holder would drain excess liquid down the toothbrush handle.

[0006] U.S. Pat. No. 5,687,855 relates to a disposable toothbrush holder that holds toothbrushes upright, bristle-end upwards, for sanitary drying, supported in circular apertures in a convex upper portion supported by integrally-formed legs. This holder also stores a toothbrush oriented such that excess liquid drains down the toothbrush handle.

[0007] GB 2319176 relates to a toothbrush holder comprising a rack and vessels suitable for holding a sterilising liquid. A toothbrush is stored with bristles downward and located within a vessel. The rack maintains each toothbrush in a position whereby the bristles remain in the vessel. This holder is suitable if a sterilising liquid is used.

[0008] EP 974288 relates to a toothbrush holder comprising a recess or aperture in a wall suitable to insert and support a terminal-end of a toothbrush with a slender handle in a cantilever-like manner. The toothbrush is held at an acute angle to the wall and suspended therefrom above and spaced from a drainage surface.

[0009] The above referenced U.S. Pat. Nos. 4,978,003; 5,769,245 and 5,687,855 relate to holders for storing toothbrushes with bristle-ends upward and thus excess liquid drains down the toothbrush handles when stored therein. Storing a toothbrush in this orientation may be particularly undesirable for an electrical toothbrush having electrical components in the handle. The toothbrush holders described in GB 2319176 and EP 974288 relate to holders for storing toothbrushes with bristle-end downward. The holder described in GB 2319176 is complicated in use because of a necessity for using vessels containing sterilising liquid. The holder described in EP 974288 is suitable for toothbrushes with slender handles and could not be used with a toothbrush having an enlarged handle such as a battery operated toothbrush.

OBJECT OF THE INVENTION

[0010] It is an object of the invention to provide a holder for storing a toothbrush having an enlarged handle with the bristle-end located downward which alleviates one or more of the disadvantages of the prior art.
